Glass ceramics which contain apatite crystals are used as implant materials in medicine. Because most of these glass ceramics are comprised of fluoride-containing glass compositions, the apatites should be fluoride-containing apatites. The fluorine content of these apatites is important for medical applications. The purpose of the current study was to determine the possibilities of measuring the fluorine content of these apatites. High resolution solid state 19F Magic Angle Spinning (MAS) Nuclear Magnetic Resonance (NMR) spectra of apatite-containing glass ceramics have been obtained. Using the correlation between the isotropic 19F chemical shift and the fluorine content, it was possible to determine the fluorine content of the apatites.
含有磷灰石晶体的微晶玻璃被用作医学中的植入材料。由于这些微晶玻璃大多由含氟玻璃组合物构成，所以磷灰石应为含氟磷灰石。这些磷灰石的氟含量对于医学应用很重要。本研究的目的是确定测量这些磷灰石氟含量的可能性。现已获得了含磷灰石微晶玻璃的高分辨率固态19F魔角旋转（MAS）核磁共振（NMR）光谱。利用各向同性19F化学位移与氟含量之间的相关性，可以确定磷灰石的氟含量。
